The report, published online in The New England Journal of Medicine on Wednesday, analyzed the coffee-drinking habits of more than 400,000 men and women ages 50 to 71, making it the largest-ever study of the relationship between coffee consumption and health.

Previous studies have offered conflicting results on the relative benefits or harms associated with regular coffee consumption. While coffee contains caffeine, a stimulant that may temporarily increase heart rate and blood pressure in some people, coffee also contains hundreds of unique compounds and antioxidants that may confer health benefits. Further confusing much of the research into coffee is the fact that many coffee drinkers are also smokers, and it has been difficult to untangle the relative health effects of coffee and cigarettes.

To learn more, researchers from the National Institutes of Health analyzed diet and health information collected from questionnaires filled out by 229,119 men and 173,141 women who were members of the American Association of Retired Persons (AARP) between 1995 and 1996. The respondents were followed until 2008, by which point 52,000 had died.

Over all, the risk of dying during the 14-year study period was about 10 percent lower for men and about 15 percent lower for women who drank anywhere from two cups to six or more cups of coffee a day. The association between coffee and lower risk of dying was similar whether the coffee drinker consumed caffeinated or decaffeinated coffee.

I’ll admit those last three words don’t exactly warm my heart, but I’ll ignore that and go downstairs and get another cup of joe (yes, right now my office floor is sans coffee maker. The horror!)
